Hi all,<\/p>\n

when running a basic analysis on a bolted connection based on 2 C shaped brackets (one fixed and one pulled away by applying a force on it) I realized that the revolute joint works as if the virtual pin was “glued” along the whole circumference: hence half of the virtual pin causes tension on one side of the hole and the other side causes compression. In reality, the pin surface cannot pull along the surface of the hole, it can only push and compress so the actual stress distribution to be expected I believe is one side totally unloaded (as a matter of fact a small gap will be created) and the other half circumference will see pure compression.<\/p>\n

What settings should be applied to the revolute pin to allow only for compression on the nodes?<\/p>\n

I know one solution would be to split the hole surface into two but that would require to know in advance the direction of the resultant force which is easy in this simple example but much more complicated in some types of joints I need to analyze<\/p>\n
